I don't know what you would call an office of the President-Elect, except "Office of the President-Elect."
As the President-Elect Joe Biden speaks to the county to prepare for the initiative to end the COVID-19 crisis, he should consider the importance of multi-language communication. He can't write Executive Orders yet, but, the law does require any and all healthcare information to be made available through any language currently used in the USA. His HHS Secretary needs to prepare the speeches available in multiple languages.
This initiative of providing information in multi-languages began with the HIV/AIDS crisis. There were entire communities left out of the information to prevent that virus and subsequent illness cue to language barriers. So, as the President-Elect prepares to lead to end the spread of SARS-CoV-2 his speeches should be made available in different languages to help stem the spread. Often those translations, if even on paper, are read by people of other countries and helps them carry out vital policies as well.
